About me

Hello my name is Emily Reitz. I'm very talkative and like meeting new people. I am adopted and have a twin and also an older sister. I'm into a lot of sports; volleyball, basketball, track and softball.external image Photo%20on%202010-09-21%20at%2010.21.jpg

Butternut (White Walnut):

-Juglans cinerea
-fungal disease killed many butternut trees
-nuts for wildlife
-furniture, instrument cases, and boxes
-buartnut they both have nuts on the trees
-Stout, greenish-gray to tan, rough, brittle. Pith chocolate-brown, chambered. Buds light brown, hairy, not covered with scales; end bud 1⁄2"-3⁄4" long, side buds smaller. Fringe of short hairs between leaf-scar and bud.
-native to the eastern United States and southeast Canada, from southern Quebec west to Minnesota, south to northern Alabama and southwest to northern Arkansas.

Silk:

Silk fabric was first grown in ancient China.

Silk is made for fabric in Chinese merchants because of its texture and luster. Silk was used for many of things like clothing such as shirts, ties, blouses, formal-dresses. Other things would be bed-sheet, blanket, tables and pillow.

Interesting thing about silk is that it is a natural protein fibre, some forms of which can be woven into textiles. Silk fabric was first developed in ancient China.

Diffusion and Osmosis:

The salt water took the water out of the potato so now it weighs less and the potato shank and turned brownish.

The pure water made the potato turn a yellowish color and gained a little weight.

The salt water potato experiment showed diffusion while the regular water potato experiment showed osmosis.

The DNA starts to unwind.

The hydrogen bond are broken.

The strand 1 is going to get a new strand 2.

The strand 2 is going to get a new strand 1.

The hydrogen bonds reform, and DNA winds back together.

Telomeres -long stretches at the ends of the chromosome
okazaki fragments - DNA polymerase can begin to synthesize a section of complementary strand, working in a different direction
dna ligase -stitches the okazaki fragments together
telomerase -enzyme that adds telomere repeat sequences to the three end of DNA strands
cancer -arise from somatic cells, and they regained the ability to synthesize high levels of telomerase with shorten their telomeres
transplanted cells- required periodic fresh infusions of their transformed T cells
cloning –DNA placed in a organism so there is enough analyze or use in protein production
aging -progressive loss of physiological functions that increases the probability of death
